Perkhorovich continued to serve in the interwar period, but was dismissed from the Red Army during the Great Purge.

Postwar, Perkhorovich continued to serve, becoming chief of the General Staff's Combat Training Directorate before his 1951 retirement.

In March 1915, Perkhorovich was drafted into the Imperial Russian Army as a private and was assigned to the 232nd Reserve Infantry Battalion at Kharkov, where he graduated from training courses and became a junior unteroffizier.

He was the regimental adjutant until February 1920, during which the division fought near Pinsk, Mozyr, and Korosten against the Ukrainian People's Army and partisans in Belarus and Ukraine until the spring of 1919.

Perkhorovich served in the Soviet offensive on Minsk and the Battle of Warsaw, then took part in the elimination of Stanisław Bułak-Bałachowicz's attempted Belarusian national uprising until November of that year.

He was dismissed from the Red Army in August 1938, during the Great Purge, but was reinstated in November 1939, becoming a teacher in the combat training department at the State Central Institute of Physical Education in December.

[1][3] In May 1942, Perkhorovich took command of the 100th Rifle Division, part of the Arkhangelsk Military District, which in July moved to the Voronezh Front's 40th Army.

He led the division in the heavy defensive fighting around Voronezh in the fall and was promoted to Major General on 20 December.

During the first two days of the attack, the army eliminated heavily fortified German positions between the Vistula and the Western Bug, then crossed the Vistula and emerged in the rear of German troops defending Warsaw, playing a major role in the rapid capture of the city.

Developing the offensive, the army rapidly moved west and by the end of the month had advanced 500 kilometers and reached the Oder.

For his leadership, Perkhorovich was awarded the title Hero of the Soviet Union and the Order of Lenin on 6 April.

Due to illness he was not able to graduate, but in April 1947, Perkhorovich became chief of the General Staff's Combat Training Directorate.
